Title: Temperature compensation type crystal oscillator
Inventor: MATSUMOTO KAZUNARI
IPC: H03B5/32
Filed: 1992-03-03
Abstract: PURPOSE:To obtain high frequency stability over a wide temperature range by devising the oscillator such that a temperature compensation element section makes analog temperature compensation and a variable capacitive element section whose capacitance is varied with a control voltage added to the temperature compensation element section makes digital temperature compensation in addition. CONSTITUTION:When temperature around a crystal vibrator 33 changes, a temperature sensor detects the change and a temperature compensation element section 32 also detects it. The temperature compensation element section 32 makes analog temperature compensation so that a frequency fluctuation of the crystal vibrator 33 is set within a range from + or -2ppm to + or -3ppm (at -30 deg.C to +80 deg.C). Then a control voltage is applied to a variable capacitive element section 31 via a digital circuit network according to the temperature information detected by the temperature sensor. Since the variable capacitance element section 31 is controlled by the control voltage, the frequency fluctuation of the crystal vibrator 33 is set within a range of + or -0.15ppm (at -30 deg.C to +80 deg.C).

Title: Solar angle determining device for satellite
Inventor: INAGAWA YOSHIYUKI
IPC: G01C1/00
Filed: 1978-04-18
Abstract: PURPOSE:To obtain all the necessary information for positioning a satellite without any use of a solar sensor by using a special satellite sensor. CONSTITUTION:There is prepared a satellite sensor 5, in which a different is established between the sensor output levels from the day and night sides of a satellite and by which the reflected light from those sides by the action of the solar light is discriminated. The satellite sensor 5 is connected with an A/D converter 6 and a circuit 7 for determining the width of the earth and a spin rate. As a result, the output of the sensor 5 is differentiated by a determing circuit 7 into leading edge signals and into trailing edge signals. The pulse generation is accomplished in response to the former signals whereas the pulse interruption is accomplished in response to the latter signals. Thus, the width of the satellite and the pulse train are expressed to generate an output B. And, pulse output A for determining the width of the satellite at the day (and night) sides is generated. As a result, it is possible to determine the solar angle merely by attaching the two satellite sensors 5 in the reference directions of + and - sides to the normal plane of a spin stabilizing type satellite.
